一、1、在引導讓步狀語從句的從屬連詞中,比較常見的有although, though, even though, even if, whether…or…等。
2、另外,以-ever結尾的連詞如however, whatever, whoever, whenever, wherever等也可引導讓步狀語從句,其用法相當于no matter…。
3、注意,while和when除用于引導時間狀語從句外,有時也可引導讓步狀語從句,其意為“盡管”“雖然”。

二、除了上訴常見的從屬連詞引導讓步狀語從句外,as 也可以引導讓步狀語從句,但是,as引導的讓步狀語從句必須以部分倒裝的形式出現(xiàn),被倒裝的部分可以是表語、狀語或動詞原形,though也可用于這樣的結構中,但although不可以這樣用,例如:
引導讓步狀語從句時,as意為“雖然…但是”,“縱使…”之意”,“盡管”,通常從句要倒裝,倒裝的方法是將從句的表語或狀語放在as之前,而用though引導讓步狀語從句時句字則不必倒裝(口語中也可倒裝).
